<div class="textblock"><p>This is the implementation of the Primal-Dual System, using the full space approach with a direct linear solver. </p>
<p>A note on the iterative refinement: We perform at least min_refinement_steps number of iterative refinement steps. If after one iterative refinement the quality of the solution (defined in ResidualRatio) does not improve or the maximal number of iterative refinement steps is exceeded before the tolerance residual_ratio_max_ is satisfied, we first ask the linear solver to solve the system more accurately (e.g. by increasing the pivot tolerance). If that doesn't help or is not possible, we treat the system, as if it is singular (i.e. increase delta's). </p>
